HDD

Hard disk drive is the main, and usually largest data storage hardware device in a computer. The operating system, software titles, and most other files are stored in the hard disk drive.

Hard disk drive is sometimes referred to as the “C drive” due to the fact that Microsoft Windows, by default, designates the “C” drive letter to the primary partition on the primary hard disk drive in a computer.

While this is not a technically correct term to use, it is still common. For example, some computers have multiple drive letters (e.g,. C, D, and E) representing areas across one or more hard drives. The hard disk drive also goes by the name HDD (its abbreviation), hard drive, hard disk, fixed drive, fixed disk, and fixed disk drive. Regardless of what it’s called, the primary hard drive typically contains the root folder of the operating system used.

A few of the most popular hard drive manufacturers include Seagate, Western Digital, Hitachi, and Toshiba.
